When first introduced she seems happy, friendly, and acts innocent. She is head strong, hopeful, and cares deeply for the well being of others. When she is tense she bites her bottom lip like Nefertari Vivi.

After meeting the Straw Hat Pirates she becomes more and more courageous, speaking her mind and losing her fear of her people's "God" Enel as they struggled to fight him. The main reason was because of her sense of justice and morality, seemingly losing her father, and love for her people.

Conis was playing with her harp on Angel Beach when she met the Straw Hat Pirates. Seeing them, she greeted them and helped Luffy out with a fruit he was having trouble with. She then introduced herself and her pet, Su to the pirates. Figuring that they were from the Blue Sea and did not know much about Skypiea, she decided to help them. She was then greeted by her father, Pagaya, who unfortunately crashed into a tree with his waver. Seeing then that the pirates were interested at what her father rode, she began to explain what a waver is and how it works. With this, Luffy decided to try out her father's waver. However, Conis, her father, and the other Straw Hats then witnessed Luffy unfortunately flipped it over. After Luffy was fished out by Zoro, Conis and her father explained that controlling a waver was hard for most beginners. She explained that she herself that even though she had practiced since she was a child, she had just recently mastered controlling it. Conis and the others then suddenly witnessed that Nami was completely adept at riding it. She and her father then took the rest of the Straw Hats to their house for a snack while Nami continued practicing with the waver behind.[1]

Conis shows Luffy and Usopp how a Breath Dial works.

At her house, Conis began to explain how Dials work to the Straw Hats using a Tone Dial as an example. She then told them about the different types of Dials there are and how they are a crucial part of Skypiean culture. She then joined with the Straw Hats in a meal made by her father and Sanji. While they were eating, Sanji noticed that Nami was no longer around the sea near Angel Beach. With this, she and her father began to worry. She explained to the Straw Hats that she was worried that Nami might have wondered off to Upper Yard, the holy land where god Enel lives.[3] She explained to them that setting foot on Upper Yard was against Enel's will.[4]

Later as her father was taking a look at the waver that Luffy found in the St. Briss, Conis and those with her noticed the White Berets coming down to Angel Beach. When they arrived, Conis and her father learned from their captain, McKinley, that the Straw Hats are illegal trespassers in Skypiea. As McKinley was fining the Straw Hats for their crimes, Conis witnessed Nami, who had just arrived, knock McKinley for giving them such high fines with the waver she borrowed. With this McKinley decided to sentence the Straw Hats to Cloud Drifting. Upon hearing this, Conis explained to the Straw Hats that Cloud Drifting was a death penalty wherein one's crew and ship are set adrift on a separated island cloud to die. With that she told the Straw Hats to run. Just as the White Berets started to attack the Straw Hats, Conis and her father witnessed Luffy's Devil Fruit powers and witnessed him and two of his crew defeat the White Berets. With this turn of events, Conis and her father then learned that the Straw Hats were sentenced to be judged by the priests of Upper Yard.[5]

As the Straw Hats discussed what to do next about their current situation, Conis was asked if there was a safe way back to the Blue Sea below. She explained to them that they could get back through Cloud's End however due to the sky ocean being very big they may not be able to get there in time. Conis then went back to her house with her father and some of the Straw Hats to help prepare for the pirates' trip. Just then she and the others witnessed the Going Merry being taken to the Sacrificial Altar by a Super Express Speed Shrimp. After the three remaining Straw Hats were explained by her father what had just happened, Conis then led them to the Angel Island Port where they could get a Dial boat for their trip into Upper Yard. As they went there, Conis explained a bit more of Skypiean culture as they traversed through Lovely Street. As they arrived at the port, Conis showed them the boat they would use, the Karasumaru. Despite Luffy not liking the boat, they accepted.[6]

Conis tells the three remaining Straw Hats of what she did.

As Conis further explained how they could get to Upper Yard, Luffy suddenly asked her why she had been shaking ever since they left her house. As she was asked that question and as further question arose in the conversation whether or not she will be safe after the Straw Hats left, Conis could not bare it any longer and told them it was her that called for the Super Express Speed Shrimp to take the Going Merry away. She then explained to them that it was her people's "civic responsibility" under Enel's rule to take them to Upper Yard to be judged. If they did not do so, they would be killed.

As she apologized, the three Straw Hats then asked her out loud if that was going to happen to her then why did she tell them that because now she was going to be targeted. Just as they were talking, Enel decided to punish Conis for talking with El Thor. Seeing what was happening, Luffy quickly grabbed Conis in order to get her out of the lightning wave. Despite not being able to dodge the wave, Conis and Luffy were fortunately saved by Gan Fall and Pierre, who showed up in the nick of time. With her saved, Gan Fall decided to take her to his home to protect her. As Pierre flew back to Gan Fall's home, Conis asked the former god to return.[7]

Having been saved by Gan Fall, Conis and her father were taken to the former god's home for protection. As she was sadly playing her harp, Gan Fall explained to her what pirates are and what that Luffy's crew were this type of people to begin with. Despite this however, Gan Fall explained to Conis and her father that the Straw Hats were probably just good people who do not follow the rules rather than outright criminals. He explained to them he too had a pirate for friend about more than twenty years ago when was still the god of Skypiea. As the discussion flowed, the former god discussed with Conis and her father of long the war had been in Skypiea. Conis was then told by Gan Fall about the legend that when Upper Yard sings the beautiful song that was heard when it was created, the war happening in Skypiea would end. As Conis and her father talked with the former god, Gan Fall suddenly had to leave them as Pierre called out to him. As she drank some pumpkin juice and watched Gan Fall and Pierre fly away, Conis expressed to her father how good the drink was.[8]

Conis and her father are joined by Aisa on their way to Upper Yard.

As Conis and her father stayed in Gun Fall's home, Pagaya decided to that they should aid the Straw Hats by fixing up the waver they found. After a day of fixing up the waver, the two then went to Upper Yard to help the Straw Hats via a rather loud waver. Along the way, they rescued a little Shandia girl named Aisa whose waver was broken and was being attacked by a Sky Fish. With the help of Aisa's Mantra ability and some Cloud Dials, Conis and her father were able to find the Straw Hats' ship within the deep forest of Upper Yard. Onboard the Going Merry, she found out that both Usopp and Sanji had been completely electrocuted. Seeing them at such a state, she immediately tended to their wounds.[9][10]

After giving Nami the repaired waver, Conis and her father witnessed Aisa was again try to go off on her to save her friends. However in the middle of a little scuffle between Aisa and Nami, Conis and the others suddenly realized that a giant snake was in front of them. The giant beast then all of a sudden gave started acting violently as if in pain which caused Nami drive back into the forest on her waver with Aisa hanging on for life. As the snake followed the two, Conis and her father were left on the Going Merry to guide the ship and take care of the two injured Straw Hats.[11]

Pagaya shoves Conis out of harm's way.

As Conis and her father continued guiding the Going Merry through Upper Yard, the two were alerted by Su who had spotted an injured Skypiean. The man who was originally part of Enel's Enforcers told them about Enel's plan to destroy all of Skypiea. As he told them this, Enel decided to attack them with El Thor. Conis was fortunately pushed away from the lightning wave by her father. Her father however did not escape in time. Despite what had happened, Conis decided to warn her people at Angel Island of Enel's plan and left Su to take care of the injured Straw Hats.[12]

After traversing across the White White Sea on her father's noisy waver, she had finally reached Angel Island. However when she arrived there, the White Berets were ready to arrest her for helping the Straw Hats, and were preventing her to go any further. As a result, Conis had to unfortunately ram her waver through McKinley. Upon getting off her waver Conis tried to convince the frightened residents to leave through Cloud's End because Enel was planning to destroy all of Skypiea. Despite this she was still doubted by the people because she believed in Enel that she stated out loud that Enel was no god. At this utterance of this blasphemous statement, everybody ran away from her expecting her to be punished by Enel. She however wasn't struck down by Enel and at further risk of being killed by him, Conis further explained the situation to the people. She also explained that before they pray and wait for a miracle, they see the reality before their eyes because all that Enel ever brought to them was despair.[13][14]

Having convinced the residents of Angel Island to leave Skypiea, Conis was then approached by various families and questioned on what had happened to their loved ones that served under Enel as his Enforcers. Fearing that their family members may have been all killed, Conis was unable to answer them. Fortunately, McKinley stepped in and stated to the people that he and the White Berets would look for their family members. McKinley then explained to Conis why he and his men worked for Enel. He explained to her that he had hoped that if Enel's rules were followed that nobody would be hurt and an incident like what happened to Enel's homeland, Bilka, would not be repeated. Hearing this, Conis however forgave McKinley as she believed what he was doing wasn't wrong at all. She then hopped aboard her waver and headed back to the Going Merry to continue helping the Straw Hats.[15]

Conis witnesses her prayers being answered as Luffy defeats Enel.

By the time Conis had reached back to Upper Yard, she noticed flying high above, the ark that was built for Enel that the man from earlier mentioned, the Maxim. When she came back to the Going Merry, she was surprised to find out that the two injured Straw Hats were missing.[16] From what she could interpret from some pantomime gestures from Su, Conis learned that the two had gone up to the Maxim despite being badly injured. Unable to do anything else but stand there for the moment, Conis hoped that everyone was okay.[17]

As she watched her home be slowly destroyed by Enel's powers, she wondered if there really was a God. Just as Enel delivered a gigantic apocalyptic thunder cloud, Raigo, to completely obliterate all of Skypiea, Conis started praying for a miracle along with the rest of those who lived in Skypiea.[18] And sure enough their prayers were answered. Conis and the rest of Skypiea witnessed Luffy completely destabilize Enel's attack. They all then witnessed Luffy finally defeat Enel by punching the god straight into the golden bell. As the golden bell was hit, Conis and everybody heard its beautiful sound, the sound that signaled the end of the four hundred year war.[19]

After having heard the beautiful sound of the Golden Bell and witnessing Enel and his ark fall into the White White Sea, Conis was then joined up by Luffy and Nami. Together, she went with them to the rest of Luffy's crew in the Shandora ruins. On the way, they discovered where Enel's Priests store their food. With a large bag of food gathered from the food storage, Conis and the two Straw Hats arrived where everyone else was. There she expressed how glad she was since she was so worried of everybody's safety. As she was greeted by the rest of the Straw Hats, Conis was asked where her father, Pagaya, was. She sadly told them that he tried to protect her from Enel's attack and could not get away. Surprisingly then, her father showed up out of nowhere to hilariously mourn alongside the rest of them of his supposed death. A tearful and relieved Conis was then explained by father that he simply fell to the White Sea below when they were attacked by Enel.[20]

After having been reunited with her father, Conis then came within a ruin and to help take care of the various wounded Skypieans and Shadia from Enel's survival game. By the time night fell she was taking care of the wounds of a Shandia warrior, Wiper. As the warrior woke up, she told him to rest a bit since his wounds weren't healed yet. Together with Gan Fall and the Shandia chief, she showed Wiper the celebration shared by both Skypiean and Shandia alike held around a huge bonfire where Giant Jack used to be.

Conis picnicking with her new friends.

After several days of festivities, Conis and her father then guided the Straw Hats and their ship to Cloud's End. As she and her father said their farewells to the Straw Hats, she wished them good luck in going back down to the Blue Sea. She then summoned an Octopus Balloon to aid them in going down.[21]

After the incidents with the Straw Hats and Enel, Conis and her father then decided to live in Upper Yard along with the rest of the Skypieans and Shandia. Having made peace with one another, both Conis' people and the people of Shandia agreed that can live together and share Upper Yard with one another. With this Conis and her father were able to live in their new home, peaceful without war and an oppressive god. With peace spread throughout all of Skypiea, Conis could thus walk around and have picnics with her new friends without worries. Among of her new found friends were Aisa, Laki, and Nola, the gigantic snake of Skypiea.[22]

Originally in the manga, when Conis tried to convince the residents of Angel Island that Enel was planning to destroy Skypiea, a kid, whose father was in Enel's militia, threw a rock at her. In the anime during the same scene, the same kid instead threw a tomato at her. This was done in order to tone down the original scene's violence done by the kid towards Conis.

Also originally in the manga, Conis was able to convince the residents without using her bazooka at all. In the anime however, she was met with some doubters that she was forced to fire her bazooka in the air to make a point.[23][24]
